My heater was blowing cold air. So we back flushed the radiator and put new in antifreeze and it worked when we test drove it. Then I went on a longer drive and it worked for the first minute or less and then blew cold air after that. Yesterday when I drove it I got back in after driving a long distance and for the first minute or less it was hot air that turned cold. I have a 2001 Jeep Grand Cherokee V8. Does anyone have any other ideas. Does it matter what antifreeze you use? It said it

Why would my 2002 Jeep Grand Cherokee only blow luke-warm to cold air when the fan is on high? First the heat went on the highest setting, so i used the second highest. Then it started to coll as well...now the two highest fan setting will not blow hot air. Also, I don't seem to get a lot of air on my feet, regardless of the setting. I had my heater core done in August of this year. Would this have anything to do with it? Could something be off from when they had the whole dash off? I can't real

I have a 2002 Jeep Grand Cherokee Limited with the automatic climate control option. Within the last few weeks, I have noticed cold air seeping under the passenger side dashboard, near the blower mechanism. It seems that the faster you drive, the more air comes in. I checked the heater operation and found that it does blow hot air out of the floor vent at the same time, so the climate control is operating correctly. Could there be a poor seal around the blower assembly. Any help would be appreci

I have an 01 Jeep Grand Cherokee. When you turn on the air conditioning air does not blow out any of the vents except a small amount of air (cold) will blow out the defroster vents by the windshield.
